A new video shows the aftermath of the fatal shooting of two NYPD officers, who were killed in New York City Saturday, in what officials called an "execution style" assassination. The attack, carried out by 28-year-old Ismaaiyl Brinsley, took place in the Bedford-Stuyvesant area of Brooklyn.

The footage (see above), taken from a nearby apartment on the corner of Tompkins and Myrtle Avenues in Brooklyn, shows the massive emergency response immediately following the attack. Moments after the shooting, dozens of emergency responders arrived at the grisly scene. Some can be seen performing CPR on the victims.

The two officers, Wenjian Liu and Rafael Ramos, were then rushed to the hospital. Neither survived.

Brinsley fled the scene immediately after the attack, and later killed himself in a nearby G train subway station.
